25th of September 1991

The British Aerospace regional turbo-prop Jetstream 41 made its first flight on this day in 1991.

The Jetstream 41 prototype

The history of the designation Jetstream 41 goes back to the 1950s and the British aircraft manufacturer Handley Page, had a design concept with that name. When Handley Page collapsed in 1970, the project continued with Scottish Aviation. They in turn ended up, after several mergers and a privatisation being incorporated in British Aerospace (BAe).

BAe adopted the 'Jetstream'name for its twin turboprop line of regional aircraft.

The first prototype was rolled out of the factory at Prestwick (UK) on the 27th of March 1971, in total there would be 4 prototype aircraft, The first production aircraft went into service with Manx Airlines in November 1992.

The Jetstream 41 was aimed at the same market as the Embraer Brasilia and Saab 340. It had a new fuselage design which was stretched compared to its smaller predecessor the Jetstream 31 but had a 16 feet (4.88 meters) stretched fuselage. This was done by adding a 8' 3" plug forward of the wing and a 7' 9" plug aft of the wing.

Also the wing was changed, the span increased an aileron and flaps were newly designed. Compared to the Jetstream 31 another big difference was that the fuselage was mounted on top of the fuselage. This solved the "problem" on the Jetstream 31 that had its wing spar running through the cabin which was a real trip hazard. Another benefit of the fuselage being mounted on the wing it created extra baggage capacity in the (enlarged) wing to body fairings.

As powerplant the Allied Signal TPE331−14 engines were selected, the initial version was rated at 1500 shp, later models were rated at 1650 shp. Also, the flightdeck received an update besides new windows also the flightinstruments were presented on an EFIS setup.

In 1986 the Jetstream 41 program became part of the marketing consortium consisting of ATR, Aérospatiale, Alenia and BAe. Although a success in sales in mid-1997 BAe announced it would stop the jetstream program, at that time 100 airframes were delivered. On the 19th of February 1998, the last aircraft, s/n G-4-104) left the Prestwick factory, after completion, it would be delivered to the Hong Kong Government. According to, in July 2018 51 Jetstreams were still operational. Specifications for the Jetstream 41:
